Sources de courant alternatif et continu
Lake Shore CryotronicsCes sources de courant AC et DC à très faible bruit, très stables et programmables sont proposées avec la technologie MeasureReady. Ce sont des instruments de précision qui peuvent être utilisés dans des configurations de table ou montés sur rack. Ils sont idéaux pour tester, mesurer et faire fonctionner des dispositifs résistifs et semi-conducteurs, tels que les capteurs de température Cernox, les RTD, les capteurs au silicium, les dispositifs LED et les capteurs à effet Hall.
- DC et AC/DC à faible bruit
- Source de tension et de courant
- Interface utilisateur simple
- Connectivité Wi-Fi, USB et LAN (option GPIB)

155 AC/DC Current and Voltage Source
In most cases AC as well as DC excitation signals should have as low source noise as possible. However usually DC noise performance is compromised to ensure high AC noise performance and vice versa. This is because of the filtering, that not only quiet DC noise but also dampens AC signals. The 155 system was engineered to achieve low-noise levels without additional filtering, enabling exceptional output performance in both DC and AC modes. Which could be used to successfully perform I/V curve, Hall effect, resistance, resistivity, and other fundamental measurements of novel materials and early-stage devices.
The 155 generates just 200 nV RMS (1 µV p-p) of low frequency (<10 Hz) noise and 9 µV RMS of higher frequency (10 Hz to 100 kHz) noise in the 10 mV range. With a programming resolution of 100 nV, the 155 is ideal when a very clean, ultra-low voltage output is required. For low current signals, the 155 precision source is equally capable —just 7 pA RMS of low frequency noise and a very low 1 nA RMS of higher frequency noise in the 1 µA range, with a 10 pA setting resolution.
